Umm... I didn't get the ending!(￣∇￣") someone please explain!!

Yamamotocchi heard the guys talking about Todo's teenie weenie problem, so he shaved his own pubes off to go and start the "look I've had similar issues, let's train you up" situation - sneaky sneaky! Basically, Yamamoto liked Todo from the very beginning.

I see! Thanks for explaining (づ￣ ³￣)づ

No worries! ヾ(❀╹◡╹)ﾉ~
